Bed-wetting, or involuntary nighttime urination, is a common occurrence for many children. It’s often simply a developmental stage, though an embarrassing one. It is most common for children under the age of 6 or 7, and most will outgrow it beyond this age. Between ages 8 and 11, fewer than 5% of children continue to have a problem with bed-wetting. It’s generally not a cause for concern because nighttime bladder control may not yet be established.
Frequent urination can have wide-ranging causes, whether due to a medical condition such as diabetes or a neurological disorder, or from poor kidney function, urinary tract inflammation, bladder infection, or certain medications. In many cases, doctors are unable to exactly identify what’s causing this symptom but nonetheless it can be an uncomfortable and difficult problem to live with.
